[QUOTE=sabbanick;10906583]On the solo DL is there an actually calibration mode that it goes into?

When I select it a screen briefly comes up stating its resetting it and thats it.

Randy--are you referring to telling the Solo, via the ECU configuration, that it needs to calculate the gears by going through the "driving around" calibration process which I've previously described, or do you mean that the Z4M ECU protocol that we're all pushing from RS2 to the Solo already contains the speed-rpm relationships needed to determine the gears, making the "driving around' process unnecessary? (Does that question even make sense? I pity the other guys reading this thread, who without having a Solo they're grappling with, wonder what the hell the four of us are talking about...)

If we do, indeed, still need to "drive around", I recall the Solo timing out of calibration mode very quickly--so find a deserted road where you can stop, put the Solo in calibration mode and immediately move off in 1st. Then, engage each gear for 5-6 seconds before you come to a stop.

Result is the same.

Randy did you finally get the Solo DL to read your gears?
Sitting here on the couch, I get the same "ERR" message, but mine has worked fine once I finally got a successful calibration drive done.

Do you mean you're driving around with the Solo connected to your laptop and to the CAN cable, and you're getting the error?

Looking at Randy's file that's posted on TrailBrake, he does have calculated gear data. I'm having a heard time making sense of it, though. Randy--did it look accurate to you?

Boy, I didn't think we'd have so much trouble with this channel!

Calculated gear selection???? maybe.
Definitely calculated--no direct data. Does it by examining the speed-rpm relationship, which is unique in each gear. At some point, the Solo needs to be taught (or provided) with the each gear's ratio.
